Naturally, the fact that she’s running against odds-on favourite Justin Trudeau — 41-year-old half-sibling to 21-year-old daughter Sarah — came up in the exchange, even as the author reaffirmed that she was reluctant to discuss her private life.

“I always knew that I would discuss my relationship with Pierre Trudeau at some point,” rationalized Coyne, “and in entering the race, it is part of my background that I believe Canadians are entitled to be informed about.”

But would she be getting as much attention if the book laid out every last detail rather than being coy about how she feels?

A question that wondered what the 37-years-older ex-prime minister would think about her running against his eldest son, were he alive today at age 93, was responded to with a firm “No Comment.”

The sales pitch for Unscripted in the Toronto Star promised an explanation about how Coyne’s acquaintance with Trudeau as a newly-minted 30-year-old constitutional lawyer led to their daughter being spawned six years later, a connection only confirmed when his name was discovered on the birth certificate record.

Yet the e-book evidently skimps on getting into her current state of self-awareness. A column from Margaret Wente of The Globe and Mail could only speculate upon how this particular non-stepmom might’ve related to her baby-daddy’s three sons.

Coyne was all but forced to stay on the fringes of his life — in a role likened to a “distant uncle” — right up until he died in 2000.

“He wasn’t prepared to commit to anything,” wrote Coyne. “He made it clear from the beginning that the boys were his first priority and that remarriage was out of the question.”

The days and nights that Trudeau spent as a player have been dissected before — even though they took place in an era when celebrity gossip about the private life of politicians was scant. Margaret Trudeau’s post-separation 1979 memoir, Beyond Reason, was a blockbuster confessional in its time if only due to curiosity about her intimate dalliances with Ted Kennedy and the Rolling Stones.
